Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to compare the levels of high-sensitivity C-reactive protein (hs-CRP) and carotid artery stiffness between patients with coronary slow flow phenomenon (CSFP) and those with normal coronary flow.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The coronary slow flow phenomenon (CSFP) is characterized by delayed opacification of the coronary arteries during angiography in the absence of significant epicardial coronary artery disease.

Hypothesis: High-sensitivity C-reactive protein (hs-CRP) is a well-established biomarker of systemic inflammation and has been associated with various cardiovascular conditions. Elevated hs-CRP levels have been observed in patients with CSFP, suggesting an inflammatory component in its pathogenesis. This marker not only predicts future cardiovascular events but may also reflect ongoing vascular inflammation in patients with angiographically normal coronary arteries.
